A 120mm collar with decorative socket screws. A kinky accessoire to your outfit at a party or if you want to play 'Fifty Shades' :)
The 2 parts lock together with a M3x35 socket head screw. The hinges are quite strong when printed in PLA, but are breakable in case of emergency. We have to keep it safe!
There are 2 versions, one with a solid ring attachment and one with seperate attachment.
It depends on the ring/lock you want to use…
The decorative socket screws are M5x8 and the holes should be tapped M5.
The 2 socket screws to attach the ring part are M5x16 and use a thin M5 nut on the inside of the collar. Beware that the screws are not too long and stick through the collar to avoid hurting yourself.
The top part holes at the hinges should be drilled 3.2mm to let a 3mm socket screw pass through. The bottom part should be drilled 2.5mm and tapped M3.
